3 MESSAGE TO SHAREHOLDERS Production Growth, Hedging and Reduced Costs Deliver Solid Financial and Operating Results Production for the fourth quarter of 2010 averaged 24,308 boe/d, an increase of 18% as compared to the fourth quarter of 2009, after adjusting for non-core asset dispositions. Advantage s daily production for 2010 exited at approximately 25,000 boe/d, exceeding our guidance of 24,000 boe/d due to stronger than expected well performance at Glacier. The Glacier gas plant expansion is now completed with production exceeding 100 mmcf/d and corporate production at approximately 30,000 boe/d. Funds from operations for the fourth quarter of 2010 increased 6% to $40.7 million or $0.25 per share, as compared to the $38.5 million or $0.23 per share for the third quarter of For the year ended, 2010, funds from operations was $175.1 million or $1.07 per share, a decrease from $197.7 million or $1.29 per share during 2009 attributed primarily to asset dispositions completed during the last two years. For the three months and year ended, 2010, our hedging program contributed a net gain of $9.8 million and $45.1 million to funds from operations, respectively. Advantage s hedging program has helped to stabilize and enhance our cash flow for capital reinvestment requirements. Operating costs for the fourth quarter of 2010 were $10.64/boe, a decrease of 3% as compared to $11.01/boe during the fourth quarter of Operating costs per boe for 2010 was $10.66/boe, a decrease of 12% as compared to $12.11/boe during Operating costs per boe have decreased considerably over the last several years as a result of the increasing contribution of low cost production from Glacier, the disposition of higher cost non-core assets, and the continued optimization of our other properties. We anticipate corporate operating costs will decline further in 2011 as a result of increased production at Glacier. The royalty rate for 2010 as a percentage of revenue was 14.0% as compared to 14.3% in For the fourth quarter of 2010, Advantage s royalty rate was 12.2% as compared to 13.8% for the fourth quarter of We anticipate that our corporate royalty rate will decline further due to increased production from Glacier where the effective royalty rate for a new Glacier Montney well is anticipated to be approximately 5% over the life of the well. Significant reductions in the average bank indebtedness during the last twelve months have led to a 31% decrease in total interest expense as compared to the prior year. As at, 2010, Advantage s bank debt was $290.7 million on a credit facility of $525 million with an unutilized capacity of approximately $231.4 million. A total of $148.5 million of convertible debentures remain outstanding of which $62.3 million will mature in December 2011 and the balance of $86.2 million will mature in January Capital expenditures during the fourth quarter of 2010 amounted to $68.9 million for a total of $223.3 million for the year ended, Approximately 86% of our 2010 capital program has been invested at Glacier where we successfully completed Phase II of our development program in the second quarter of The second half 2010 capital spending has been focused on our Phase III development program at Glacier which consisted of drilling 28 net (28 gross) horizontal wells and expanding our Glacier gas plant and gathering system capacity to 100 mmcf/d. Additional capital activities during 2010 included 3 net (3 gross) oil wells at Eyehill, 2.8 net (3 gross) oil and gas wells at Nevis, and 2.1 net (3 gross) oils wells at Sunset. Glacier Production Exceeding 100 mmcf/d with Additional 100 mmcf/d of Production Capacity Production performance at Glacier has been higher than anticipated with natural gas production averaging 53.3 mmcf/d for the fourth quarter of 2010 and exiting 2010 at 60 mmcf/d (10,000 boe/d), which exceeded our guidance. Phase III activities at Glacier are now substantially complete and production is exceeding 100 mmcf/d, which has progressed ahead of schedule and on-budget. An additional 100 mmcf/d (16,667 boe/d) of production capacity currently exists and additional wells will be brought onstream as required to offset declines and maintain production. Optimization of drilling and completion practices combined with improved geological knowledge at Glacier has significantly increased the horizontal well test rates through each of our development phases. The average test rate of the Upper Montney wells for Phase III was 8.4 mmcf/d with an average of 13 fracs per well, surpassing our expectations. Advantage Oil & Gas Ltd. - 3

4 Impressive Glacier Netbacks Enhanced by Low Cost Structure Operating costs at Glacier are forecast to decrease from the $2.85/boe ($0.48/mcf) during the fourth quarter of 2010 to $1.80/boe ($0.30/mcf) at 100 mmcf/d due to efficiencies created by increasing the production rate through Advantage s 100% owned Glacier gas plant and the utilization of multi-well production well pads on our contiguous land block which simplifies field operations. All Montney horizontal wells drilled at Glacier after May 1, 2010 qualify for a royalty incentive of $2.7 to $3.4 million based on a typical Glacier Montney horizontal well (total length of 4,200 to 4,500 metres). As a result, the effective royalty rate for a new Glacier Montney well is anticipated to be approximately 5% over the life of the well. The attractive royalty rates and low operating costs significantly enhances the netback and drilling economics of all of our Glacier Montney drilling locations as indicated below: $/mcf $/mcf Revenue (realized price) $4.00 $5.00 Royalties (5% royalty rate) (0.20) (0.25) Operating costs (0.30) (0.30) Netback* $3.50 $4.45 Operating netbacks exceed 87% of revenue Well Drilling Economics pre-tax rate of return * >39% >66% *Note: assumes 4.5 mmcf/d IP, 5 Bcf reserves & $5.5 million per well with total Glacier production of 100 mmcf/d Based on netbacks of $3.50/mcf and $4.45/mcf, annualized cash flows are projected to be approximately $128 million and $162 million respectively, which are in excess of estimated capital requirements to maintain a 100 mmcf/d production rate at Glacier. In summary, Glacier is a unique asset which provides the opportunity for Advantage to develop a large, scalable natural gas resource play which contains decades of drilling inventory and with one of the lowest cost structures in the Western Canadian Sedimentary Basin. Commodity Hedging Program Advantage s hedging program includes 25% of our forecast net natural gas production for 2011 hedged at an average price of Cdn$6.30 AECO per mcf and 34% of forecast net crude oil production for 2011 at Cdn$88.90 per bbl. Additional details on our hedging program are available at our website at Creation of Longview Oil Corp. On March 7, 2011, Advantage announced that Longview Oil Corp. ( Longview ), a wholly-owned subsidiary of the Corporation, filed a preliminary prospectus on March 4, 2011 for an initial public offering (the Offering ), which is targeted to raise gross proceeds of $150 million prior to an over-allotment option of up to 15% of the base offering size, exercisable 30 days following the closing of the Offering. The closing of the Offering is expected to occur in April, Concurrent with closing of the Offering, Longview will purchase certain oil-weighted assets from Advantage with fourth quarter 2010 average production of 6,220 boe/d (74% oil & NGLs), proved reserves of 20.1 mmboe and proved plus probable reserves of 36.9 mmboe. Advantage will receive consideration comprised of the net proceeds of the Offering, common shares of Longview and proceeds of $100 million to be drawn from an independent Longview credit facility to be established at closing. Advantage plans to use the cash proceeds from the transaction to reduce outstanding bank indebtedness. Advantage will retain an equity ownership interest of approximately 68% of the common shares of Longview (approximately 63% if the over-allotment option is exercised in full). The transaction is conditional upon customary industry conditions including the approval of the Board of Directors of Advantage. As a result of the successful completion of the transaction, historical financial and operating performance as well as forward-looking information may not be indicative of actual future performance. For further details, please refer to the press release issued by Advantage on March 7, 2011 and the preliminary prospectus filed by Longview on March 4, 2011, which are available at and Advantage s website Advantage Oil & Gas Ltd. - 4

5 Looking Forward Drilling results at our cornerstone Glacier property have demonstrated that our Montney development is among the top tier natural gas resource developments in North America. The attractive cost structure at Glacier which includes low operating costs and low royalty rates combined with a multi-decade drilling inventory provides a strong foundation to drive future development beyond 100 mmcf/d of production. With the expansion of Glacier to 100 mmcf/d now completed, a review of well performance, facility capacity and actual costs will be undertaken by Advantage to assess the timing and capital requirements for the next phase of growth at Glacier. Advantage will provide additional corporate guidance and communicate future development plans on or about mid-year Advantage Oil & Gas Ltd. - 5

6 Reserves Advantage engaged our independent qualified reserves evaluator Sproule Associates Ltd. ( Sproule ) to update the reserves analysis for the Company in accordance with National Instrument and the COGE Handbook.

For continuity, Advantage has presented herein FD&A costs calculated both excluding and including FDC. (2) The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated future development costs generally will not reflect total finding and development costs related to reserves additions for that year. Changes in forecast FDC occur annually as a result of development activities, acquisition and disposition activities and capital cost estimates that reflect Sproule s best estimate of what it will cost to bring the proved undeveloped and probable reserves on production. (3) In all cases, the FD&A number is calculated by dividing the identified capital expenditures by the applicable reserve additions. Boes may be misleading, particularly if used in isolation. A boe conversion ratio of 6 MCF:1 BBL is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

This MD&A discusses historical financial and operating performance as well as forward-looking information for the Corporation excluding any potential impacts that may occur due to the successful completion of the transaction with Longview Oil Corp. (see section Creation of Longview Oil Corp. ). As a result, historical financial and operating performance as well as forward-looking information may not be indicative of actual future performance. Non-GAAP Measures The Corporation discloses several financial measures in the MD&A that do not have any standardized meaning prescribed under GAAP. These financial measures include funds from operations and cash netbacks. Management believes that these financial measures are useful supplemental information to analyze operating performance and provide an indication of the results generated by the Corporation s principal business activities prior to the consideration of how those activities are financed or how the results are taxed. Investors should be cautioned that these measures should not be construed as an alternative to net income, cash provided by operating activities or other measures of financial performance as determined in accordance with GAAP. Advantage s method of calculating these measures may differ from other companies, and accordingly, they may not be comparable to similar measures used by other companies. Funds from operations, as presented, is based on cash provided by operating activities before expenditures on asset retirement and changes in non-cash working capital. Cash netbacks are dependent on the determination of funds from operations and include the primary cash revenues and expenses on a per boe basis that comprise funds from operations. Funds from operations reconciled to cash provided by operating activities is as follows: Three months ended Year ended ($000) % change % change Cash provided by operating activities $ 55,268 $ 39, % $ 202,494 $ 170, % Expenditures on asset retirement 1, % 6,275 5, % Changes in non-cash working capital (16,335) 7,951 (305) % (33,630) 21,349 (258) % Funds from operations $ 40,744 $ 48,281 (16) % $ 175,139 $ 197,675 (11) % Advantage Oil & Gas Ltd. - 11

Our financial and operating results during 2009 and 2010 have been impacted by dispositions completed during these years. In July 2009 we closed two major asset dispositions for net proceeds of $242.1 million representing production of approximately 8,100 boe/d. On May 31 and June 3, 2010, we closed two additional asset dispositions of non-core natural gas weighted properties for net proceeds of $66.5 million and representing production of approximately 1,700 boe/d. The net proceeds from the various dispositions were utilized to reduce outstanding debt. As a result of the dispositions, total funds from operations decreased for the three months and year ended, 2010 compared to the same periods of 2009 with all revenues and expenses generally impacted. For the year ended, 2010 we continued to realize significant gains on derivatives which amounted to $45.1 million that has helped to offset the continued weak natural gas prices and positively impact funds from operations. Hedging gains in 2010 were lower than 2009 as we had a lower percentage of natural gas production hedged at lower average prices. Funds from operations has also benefited during this year from higher crude oil prices and continued cost reductions, such as operating costs and interest expense. Unfortunately, natural gas prices still remain weak and pose a continuing challenge to the entire natural gas industry. When comparing the current quarter to the third quarter of 2010, our funds from operations per boe increased 6% to $18.21/boe from $17.19/boe as both production and crude oil prices increased, partially offset by the impact of lower natural gas prices. Funds from operations per share decreased from 2009 due to the decrease in total funds from operations and the increase in shares outstanding attributable to 17 million shares issued in July 2009 as a result of an equity offering. Cash provided by operating activities has increased during 2010 as compared to the prior year due to the decrease in funds from operations being more than offset by increases in working capital deficit. As a result of asset dispositions completed in 2009 and 2010 and changes in commodity prices, historical financial and operating performance may not be indicative of actual future performance. The primary factor that causes significant variability of the Corporation s cash provided by operating activities, funds from operations, and net income is commodity prices.

Revenue, excluding hedging, was negatively impacted for the three months and year ended, 2010, as compared to 2009, primarily due to lower production attributable to our asset dispositions that closed in the third quarter of 2009 and the second quarter of Production net of asset dispositions increased 16% for the year ended, 2010 as compared to 2009 as a result of Advantage Oil & Gas Ltd. - 12

13 our successful exploration and development activities. Natural gas revenue for 2010 benefited from significant increases to production at our Montney natural gas resource play at Glacier, Alberta where we have increased production capacity by 140% since December 31, Additional increases in production have been realized now that our facilities and infrastructure expansion work have been completed in the first quarter of Total revenue was also positively impacted by crude oil and NGLs prices, excluding hedging, that have been higher for 2010 as compared to 2009 and partially offset reduced production from asset dispositions. However, revenue has continued to be adversely impacted by natural gas prices that have been weak during the last two years due to many factors, including the recession in the North American economy that has generally reduced energy demand and higher North American natural gas production, both of which have maintained relatively high natural gas inventory levels. Given the low natural gas price environment, our commodity price risk management program has delivered realized natural gas hedging gains of $12.9 million and $55.4 million for the three months and year ended, 2010, respectively. As crude oil prices continued to strengthen throughout 2010, we realized crude oil hedging losses of $3.1 million and $10.2 million for the three months and year ended, 2010, respectively. The Corporation enters derivative contracts whereby realized hedging gains and losses partially offset commodity price fluctuations, which can positively or negatively impact revenue. The realized natural gas hedging gains have been significant and helped us stabilize cash flows and ensure that our capital expenditure program is substantially funded by such cash flows.

Production from the fourth quarter of 2009 also included approximately 1,990 boe/d related to assets disposed in After excluding production from these asset dispositions, Advantage s average daily production for the fourth quarter of 2010 increased approximately 18%, as compared to the same period of Average daily production for the fourth quarter of 2010 was comparable to the 24,287 boe/d reported in the third quarter of 2010 and our exit daily production rate for, 2010 was approximately 25,000 boe/d, exceeding our guidance of exiting the year at 24,000 boe/d. Average annual production for 2010 was lower than 2009 due to the impact of asset dispositions which was partially offset by production growth at Glacier, Alberta. During the second quarter of 2010 our new 100% working interest gas plant ( Glacier gas plant ) was brought on-stream ahead of schedule with production rates exceeding 50 mmcf/d (8,300 boe/d). Due to stronger than expected well performance, we were able to further increase Glacier production ending the year exceeding 60 mmcf/d (10,000 boe/d). This year represented another milestone in the development of our significant Montney reserves and resource potential at Glacier by increasing production capacity 140%. Phase III of our Glacier development project has progressed ahead of schedule and on-budget with production now exceeding 100 mmcf/d (16,667 boe/d). We have been very active in drilling, testing and completing wells at Glacier during the last half of 2010 and into An additional 100 mmcf/d (16,667 boe/d) of production capacity currently exists and additional wells will be brought onstream as required to offset declines and maintain production. We expect corporate production to average approximately 26,600 to 27,200 boe/d for the first half of 2011 since completing the 100 mmcf/d Glacier gas plant expansion. Advantage Oil & Gas Ltd. - 13

Our realized natural gas prices, including hedging, have decreased during 2010 as compared to 2009 as we have less natural gas production hedged for this year at lower average prices. Nevertheless, our hedging program has significantly mitigated the negative impact from lower natural gas prices and has reduced the volatility of our cash flows. During 2009 and 2010, natural gas prices have remained low from continued high US domestic natural gas production that has increased supply and the ongoing weaker North American economy that has negatively impacted demand. These factors have resulted in generally higher inventory during these years and has placed considerable downward pressure on natural gas prices. Heading into the 2009/2010 winter season, we saw strong inventory withdraws which helped to modestly strengthen prices relative to the prior lows experienced during the majority of However, as we exited the winter, natural gas prices significantly decreased and have remained weak throughout During the 2010/2011 winter we have seen respectable storage withdraws that has helped to reduce natural gas inventory to approximately the five-year average. Nevertheless, natural gas prices continue to remain weak as we exit the winter. We continue to believe in the longer-term price support for natural gas as reduced drilling for new resource based natural gas supplies and conventional natural gas will eventually reduce the supply levels. We continue to monitor these market developments closely and will be proactive in implementing an appropriate hedging strategy to mitigate the volatility in our cash flow as a result of fluctuations in natural gas prices.

The price of WTI fluctuates based on worldwide supply and demand fundamentals. There has been significant price volatility experienced over the last several years whereby WTI reached historic high levels in the first half of 2008, followed by a record decline in the latter half of the year and into early 2009, the result of demand destruction brought on by the global recession. There was Advantage Oil & Gas Ltd. - 14

15 improvement during the last half of 2009 which continued during 2010 and significantly escalated into 2011 primarily influenced by middle-east civil unrest, with WTI currently trading at approximately US$104/bbl. However, we have also seen a constant strengthening of the $US/$Canadian exchange rate during these years such that our increase in realized price has been less than the improvement in WTI. We continue to believe that the long-term pricing fundamentals for crude oil will remain strong with supply management by the OPEC cartel and strong relative demand from many developing countries, such as China and India. Commodity Price Risk The Corporation s financial results and condition will be dependent on the prices received for oil and natural gas production. Oil and natural gas prices have fluctuated widely and are determined by economic and political factors. Supply and demand factors, including weather and general economic conditions as well as conditions in other oil and natural gas regions, impact prices. Any movement in oil and natural gas prices could have an effect on the Corporation s financial condition and performance. Advantage has an established financial hedging strategy and may manage the risk associated with changes in commodity prices by entering into derivative contracts. Although these commodity price risk management activities could expose Advantage to losses or gains, entering derivative contracts helps us to stabilize cash flows and ensures that our capital expenditure program is substantially funded by such cash flows. To the extent that Advantage engages in risk management activities related to commodity prices, it will be subject to credit risk associated with counterparties with which it contracts. Credit risk is mitigated by entering into contracts with only stable, creditworthy parties and through frequent reviews of exposures to individual entities. In addition, the Corporation only enters into derivative contracts with major banks that are members of our credit facility syndicate and international energy firms to further mitigate associated credit risk. Our credit facilities also prohibit the Corporation from entering into any derivative contract where the term of such contract exceeds three years. Further, the aggregate of such contracts cannot hedge greater than 60% of total estimated petroleum and natural gas production over two years and 50% over the third year. We have historically been active in entering financial contracts to protect future cash flows and currently the Corporation has the following derivatives in place: Description of Derivative Term Volume Average Price Natural gas - AECO Fixed price April 2010 to January ,956 mcf/d Cdn$7.25/mcf Fixed price January 2011 to December ,478 mcf/d Cdn$6.24/mcf Fixed price January 2011 to December ,478 mcf/d Cdn$6.24/mcf Fixed price January 2011 to December ,478 mcf/d Cdn$6.26/mcf Crude oil WTI Fixed price April 2010 to January ,000 bbls/d Cdn$69.50/bbl Fixed price January 2011 to December ,500 bbls/d Cdn$91.05/bbl Advantage Oil & Gas Ltd. - 15

For the year ended, 2010, we recognized in income a net realized derivative gain of $45.1 million (, $86.5 million net realized derivative gain) on settled derivative contracts as a result of average market prices decreasing below our established average hedge prices. Our net realized derivative gain has decreased during 2010 as compared to 2009 as we have less natural gas production hedged for this year at lower average prices and we realized losses on our crude oil hedges as WTI prices increased. However, our successful commodity price risk management program continued to realize significant gains on derivatives for the year ended, 2010 that has helped to offset the continued weak natural gas prices and positively impact funds from operations. As at, 2010, the fair value of the derivative contracts outstanding and to be settled was a net asset of approximately $22.6 million, an increase of $5.4 million from the $17.2 million net asset recognized as at, For the year ended, 2010, this $5.4 million increase was recognized in income as an unrealized derivative gain (, 2009 $23.7 million unrealized derivative loss). The valuation of the derivatives is the estimated fair value to settle the contracts as at, 2010 and is based on pricing models, estimates, assumptions and market data available at that time. As such, the recognized amounts are not cash and the actual gains or losses realized on eventual cash settlement can vary materially due to subsequent fluctuations in commodity prices and foreign exchange rates as compared to the valuation assumptions. The Corporation does not apply hedge accounting and current accounting standards require changes in the fair value to be included in the consolidated statements of income (loss) and comprehensive income (loss) as an unrealized derivative gain or loss with a corresponding derivative asset and liability recorded on the balance sheet. These derivative contracts will settle in 2011 corresponding to when the Corporation will receive revenues from production. Advantage Oil & Gas Ltd. - 16

The Corporation currently has mineral leases with provincial governments, individuals and other companies. Royalty expense includes the impact of gas cost allowance ( GCA ), which is a reduction of royalties payable to the Alberta Provincial Government to recognize capital and operating expenditures incurred in the gathering and processing of their share of natural gas production and does not generally fluctuate with natural gas prices. Total royalties paid and royalties as a percentage of revenue decreased for the three months ended, 2010 compared to the same period of 2009 due to lower natural gas prices. For the year ended, 2010, total royalties paid decreased due to lower revenue from reduced production attributable to our asset dispositions while royalties as a percentage of revenue was comparable. Our average corporate royalty rates are significantly impacted by the Alberta Provincial Government s royalty framework that was revised effective January 1, 2009 for conventional oil, natural gas and oil sands whereby Alberta royalties are affected by depths, well production rates, and commodity prices. Additionally, the Alberta Provincial Government implemented a number of drilling incentive programs with reduced royalty rates over a period of time for qualifying wells. The majority of our wells brought on production since April 1, 2009 qualify and benefit from a 5% royalty rate on the first 500 mmcf produced or one-year, whichever occurs first, and a drilling credit of $200 per metre drilled that reduces capital spending. The drilling credit incentives are effective for qualifying wells drilled and brought on production from April 1, 2009 to March 31, 2011 while the reduced 5% royalty rate program was made a permanent incentive as of May 1, The Alberta Provincial Government also made changes in the Natural Gas Deep Drilling Program ( NGDDP ) which reduces the vertical depth requirement to 2,000 metres (from 2,500 metres) and makes the program permanent. As a result, all of our Montney horizontal wells at Glacier drilled after May 1, 2010 will qualify for the NGDDP which is estimated to provide an additional royalty incentive of $2.7 to $3.4 million for a typical horizontal well (a typical Advantage horizontal well at Glacier is 4,200 to 4,500 metres in total length). This royalty incentive results in an estimated 5 to 7% royalty rate for all Montney horizontal wells for the life of the well. This significantly lowers the natural gas price threshold required to drill economic wells and substantially improves the value of future reserves and upside potential at Glacier. We expect our corporate royalty rate to be in the range of 13% to 15% for the first half of Alberta royalty rates will continue to fluctuate based on commodity prices, individual well productivity, and our ongoing capital development plans. Operating Costs Three months ended Year ended % change % change Operating costs ($000) $ 23,787 $ 22,847 4 % $ 93,875 $ 119,022 (21) % per boe $ $ (3) % $ $ (12) % Total operating costs increased 4% for the three months ended, 2010 and decreased 21% for the year ended December 31, 2010 as compared to the same periods of The reduction in total operating costs for 2010 has been primarily due to the sale of higher cost assets, increased production from Glacier and benefits of our ongoing optimization program. Total operating costs increased modestly during the fourth quarter of 2010 as compared to the same period of 2009 due to an 8% increase in corporate production and the impact of cold weather operations. Operating costs per boe decreased 12% from 2009 to 2010 and we anticipate corporate operating costs will decline further in 2011 as a result of increasing production at Glacier. Operating costs at Glacier during the fourth quarter of 2010 decreased to approximately $2.85/boe ($0.48/mcf) which has significantly improved the netbacks realized from our Montney gas production. We estimate that operating costs at Glacier will be further reduced to a target of approximately $1.80/boe ($0.30/mcf) at 100 mmcf/d due to the efficiencies created by increasing the production rate through our 100% owned Glacier gas plant. We will seek further opportunities to improve our operating cost structure and expect corporate operating costs for the first half of 2011 to be between $8.50 and $9.00/boe.
